+### Mirroring With Harbor
+
+You can use Harbor to set up a proxy cache for Kubernetes images.
+
+From the Harbor web interface, go to "Registries" and click "New Endpoint".
+Create an endpoint `registry.k8s.io` with the endpoint URL https://registry.k8s.io.
+Go to "Projects" and click "New Project".
+Create a project named something like 'k8s', click "Proxy Cache" and select your `registry.k8s.io` endpoint.
